Pieris rapae crucivora – mating pair (Masaki Ikeda)

Why are male butterflies often more colorful than females? And if female preferences are responsible for the evolution of male colors, what benefits do females enjoy from choosing more colorful males as mates? Dr. Morehouse will tackle these topics and others related to butterfly courtship, mating and reproduction as he discusses recent insights from his research into the colorful lives of these remarkable animals.

Food Plant Guilds for our Butterflies – Presented by Jon Pelham

The plants that support the life history of two or more butterfly species, the network of living communities they belong to and some consideration of how this came/comes to be. Bio – Jon Pelham has studied butterflies since he was twelve.  He met Robert Michael Pyle in 1967 and he managed to get around Jon’s owly parts. They are colleagues and friends; he is ever grateful that Bob is willing to stand in the klieg lights of public, uh, adoration. Together they have watched their community grow into something not imagined, or hindered, by them. It was/is impossible to educate Jon – he’d rather do it himself, thank you very much! He became a LTL and PUD ‘city’ truck driver instead (less than a load, pick up and delivery). He is a Teamster for life. It supported his family and his habit and keeps him alive presently! Despite himself, the UW Burke Museum found his skills useful and, in 1972, he volunteered to study butterflies under their watch. Yes, he need(ed) watching. Jon has 5 kids, one of which he spawned, all of which he loves dearly. They spent a lot of time in the field with him. 

Jon has authored some papers but the most important thing he has accomplished is:
A catalogue of the butterflies of the United States and Canada: with a complete bibliography of the descriptive and systematic literature.  A ‘butterfly book’ with well over 600 pages and nary an image of a butterfly! That’s how he rolls! He keep it updated: A catalogue of the butterflies of the United States and Canada http://www.butterfliesofamerica.com/US-Can-Cat.htm

4/7 at 7 pm – “Stripes, bands, and blotches – Oh My”

Zoom with Dr Moria Robinson
“Stripes, bands, and blotches – Oh My! the evolution of color and pattern in caterpillars”

Register in advance for this meeting:
https://us02web.zoom.us/meeting/register/tZwrcO6oqj8iGNPXxkQPeVqRqrNFgTdScPXU

Description: Many of us fell in love with butterflies and moths for their remarkable diversity of color and pattern. Whether bright or earth-toned in color, arranged in spots or bands or irregular blotches, their appearance plays an important role: it can conceal from predators, advertise vigor for potential mates, or signal presence of distasteful or toxic compounds in their own bodies. However, while much research has focused on how and why adult butterflies and moths appear the way they do, much less attention is paid to the ‘looks’ of the immature forms. As non-reproductive larvae, moths and butterflies have a singular purpose: eat fast, get big, and metamorphose as soon as possible into an adult – without getting eaten along the way. As popular food items, caterpillars have evolved an array of strategies to avoid predators. They can be incredibly camouflaged; or they can stand out from their background, warning would-be predators away. I have been studying why this diversity of strategies has evolved. Two prominent ideas are that dietarily specialized species – those that eat only a single kind of host plant – will be more effective at sequestering toxins within their bodies, and will therefore advertise their noxiousness with warning (“aposematic”) coloration. A related hypothesis posits that species feeding on woody plants will opt for camouflage, both because woody plants tend not to produce toxins, and because there are more places to hide within an architecturally-complex shrub or tree. Other hypotheses, from the times of Darwin and Wallace, suggested that grass-feeding species should boast a stripe to help them blend in with the shape of grass blades. To test these ideas, we assembled a phylogeny (tree of life) of 1808 species of butterfly and moth in North America, for which photographs of larvae were available. We used many field guides (including from very own David Nunnallee and David James!), and categorized the colors and patterns in each species, as well as information about their diet. We were excited to find that colors and patterns can be grouped into “cryptic/camouflage” and “warning” categories, and that these colorations are related to the kind of plants caterpillars eat. We can thank the plants and the birds – the food and the predators – for the grand and beautiful parade of caterpillar appearance!

Bio: Moria Robinson is a research associate at Michigan State University, where she studies the many ways insects and plants interact. In particular, she is interested in how insects have evolved to eat the great diversity of physical, nutritive, and chemical traits found in plants, and how plants have evolved to fend off their consumers. She grew up on Vashon Island, Washington, where her interest in butterflies was encouraged by the wonderful community of WABA. She went to Middlebury College, Vermont, where she majored in biology and did a senior thesis project on host plant choice of silvery blue butterflies in suburban King County. She went on to receive her PhD from the University of California, Davis, in 2018, studying caterpillar communities in the California chaparral shrub ecosystems, and where the study she is discussing today began. When she is not stuck to her computer screen, Moria enjoys road tripping with her dog, enjoying the desert West with her partner, and photographing caterpillars on whatever plants are nearby.

3/23 at 9 am – Butterflies in the Methow with Cheryl Bellin

Introduction to Butterflies in the Methow with Cheryl Bellin, Tuesday, March 23rd, 9 AM, register here.
Hosted by Methow At Home

“Add some color to your day, join Cheryl Bellin for an introduction to Butterflies of the Methow.  She’s a lifelong butterflier, a Washington Butterfly Association board member and contributor to the Washington Butterfly database project led by Jonathan Pelham. 

We will review butterfly families and their characteristics using photographs from her garden, nearby trails, and roadsides.  Local butterflies, their host plants, and habitats will then be discussed to aid your seeing and recognizing these beauties come spring.”

Trying to generate interest, awareness locally for butterflies.  I’ll present an introduction to butterflies and feature those spring fliers that have yet to show themselves!

3/17 Zoom Meeting at 6 pm – David Jennings: Bumble Bees of Washington State

Great news!

We have a WBA meeting coming up, so mark your calendars!

Date: Wednesday, March 17th

Bumble Bees of Washington State

Come join us for this very exciting and interesting presentation by David Jennings.  He will be presenting information on the bumble bees of our state.  He is knowledgeable on bumble bee biology, ecology and identification. For the past several summers he has traveled Washington photographing bumble bees as a citizen scientist collecting data for Xerces’ Bumble Bee Watch program. David used this past summer’s restriction on field work to share what he learned by constructing a website focused on our bumble bees.  A major focus of the website is “how to ID that bumble bee”.  It also contains information on gardening, conservation and other resources.

David has an academic background in wildlife ecology and conservation and is a former Fish and Wildlife Commissioner. He serves as vice president of the Washington Butterfly Association and on the Black Hills Audubon Society’s conservation committee.

Learn them, respect them, protect them!
